As Salam n Morning to all..I`m totally a newbie for sure..from Penang. Hopefully can get some idea from the `otai's` here before purchase, especially E90. Cant afford the new ones, only secondhand year 2005-2007. Maybe u all can share some info about the maintenance, fuel consumption (can use ron95 or only ron97?), any wear and tear that might probably need to be changed..and one more thing, 320i SE vs 320i M-sport, I know the M-sport looks more `ranggi`, but the difference that I saw is only I-drive. Is there any other diff?...Sorry I`m really new in this BMW but eager to own it.Thanks everyone.
